Integrated Crop Management (ICM) There are now strong commercial pressures in many countries to reduce inputs in arable crops. This has led to the development and evaluation of less intensive and more ecologically sustainable crop husbandry methods. The success of such systems depends upon their being economically feasible. While crop protection is just one aspect of crop p ­ roduction, both ICM and organic systems require a better understanding and the effective use of beneficial organisms in order to reduce reliance on pesticides.
